The problem happens when i just rely on the wifi connection on its own and i cannot connect to the internet.I can connect through the wireless for about 5 minutes before it disconnects and stays disconnected then i have to restart the system and the same thing repeats itself.

I can connect to the internet through my laptop when i plug an ethernet cable into it which is connected directly into my ADSL unit.

Since the script you are attempting to invoke has been converted to anUpstart job, you may also use the reload(8) utility, e.g. reload smbdRTNETLINK answers: File exists-------------------------* VI. querying nslookup google.com...Server: 192.168.1.254Address: 192.168.1.254#53

I see several modules that relate to your wireless device in your lsmod. They may or may not be the source of your problem by way of conflict. I'm guessing that acer_wmi was installed by way of ndiswrapper. Sometimes blacklisting acer_wmi fixes the problem. Reboot afterwards. (You can always remove the blacklist line item to return to your previuos state.)

If you did use ndiswrapper to install your driver, was this because the driver provided in "Driver Manager" did not work?

AlsoYour ifconfig below is not showing your wireless adaptor. Perhaps this is becase the WIFI had already crashed when you ran the test. Run ifconfig when you wireless is working, then run it again after it has crashed. While crashed, runsudo ifconfig wlan0 upIf it comes up again we have another driver-problem clue.If it gives an error, it may be becasue of a block.

A few other questions:When your wireless disconects, does network manager still show it as connected ?

I cannot connect to the internet now wirelessly because it wont allow me to turn the wireless on through network settings so i have connected to the internet through ethernet cable. The wireless just stays in the off position no matter how many times u press it.

In my previous post as shown below i mentioned that windows 7 has no wifi problems at all and is extremely stable. There is no dropping or loss of connection in windows 7. Linux Mint 15 cinnamon has been my only problem connecting to wifi.

The wireless works flawlessly in windows 7 with no problems but in linux mint 15 cinnamon it is still very unstable and not working properly even after turning power management off.

The other change i made was in my network settings so it didnt try to connect to other networks it picked up.

I made it forget the connection of 10 other connections so it only focussed on connecting to my adsl incase there were any connection clashes or confusions. As it did occasionally try to connect to local wifi hot spots when it couldnt connect to my adsl.

The only thing is I am a bit nubbish when it comes to kernels. Despite looking it up and giving my best attempt, I was not able to successfully apply the patch. I don't think it should matter that all the references are to ubuntu because we use the same kernel ? (again, I am a noob with this low level stuff)

If anyone can share experience with how to apply something like this that would be swell.. or even if its possible to just compile a kernel with the patch and distribute it?

Mike open up 'synaptic package manager. In the search box type in kernel. It should list the latest stable kernel. If that is installed than you can eliminate that as a problem if it isn't the latest installed under the list of kernels, mark it for installation, apply the install by clicking the arrow, that is bent, after it installs do a reboot. Your problem very well could be from the kernel.

Hope this helps a bit but if it don't it will at least eliminate it as one of your problems. You can always type in 'uname -r' in the terminal to find out what version of the kernel you are booted into.

Pardon my ignorance, but this fix was created not 10-13 days ago. Would it already be merged with the latest kernel ?

I will give it a go either way.

EDIT: Forgot to mention, I have the latest Mint 15, cinnamon 64. It appears the latest kernel is installed.. er at least, no updates in the package manager. So basically I will either have to wait for ath9k patch to be applied to the kernel or figure it out for myself.. which may be doable now that I realized I can grab the source and headers from the package manager (derp).

Hello! I have the same issue that is posted above. I also have the exact same laptop. For me i have to turn off my WIFI and turn it back on in order to connect after it drops out. I have been using this laptop with Win 7 for more that 6 months and I wanted to go back to a Linux Distro. Im not a fan of Ubuntu after the Unity change. So this looked to be a great chance to try something new. Im also running Linux Mint 15 64 bit Cinnamon. I hope this can be resolved soon as it is quite imparative that I have Internet connection to use my laptop. I really don't want to go back to Windows. This is such a nice Distro, Im very impressed!

EDIT:for the record, I installed the 3.11-rc3-1 version and it seems to be working... just need to test a little bit more

That's the version i was using too. It also seems like blacklisting the acer-wmi module helped me a lot too. Without that my wireless still disconnected and I'd lose my bluetooth mouse on any sign of sleep. Just did a 3 hour session with no disconnects, wireless or bluetooth, and my monitor had dropped to sleep at least twice.
